-# Frontend Development Work Done
+# SmartQuery Project: Work Completed
 
-This document outlines the work done on the frontend of the SmartQuery application.
+This document provides a comprehensive summary of all work completed on the SmartQuery project to date, covering the frontend, backend, infrastructure, testing, and documentation.
 
-## Project Structure
+---
 
-The frontend is a Next.js application with a well-organized structure:
+## 1. Frontend
 
-- **`src/app`**: Contains the main pages of the application, including the landing page (`/`), login page (`/login`), and dashboard (`/dashboard`).
-- **`src/components`**: Contains reusable components, such as authentication components, layout components, and charts.
-- **`src/lib`**: Contains the core logic of the application, including the API client, authentication utilities, and type definitions.
-- **`public`**: Contains static assets, such as images and icons.
+### Tech Stack
 
-## Authentication
+- **Next.js 14** (TypeScript)
+- **Tailwind CSS** (+ DaisyUI)
+- **Zustand** for state management
+- **Recharts** for data visualization
+- **Axios** for API requests
 
-- **Google OAuth**: The application uses Google OAuth for authentication. The login page redirects the user to Google for authentication, and the callback is handled by the frontend.
-- **JWT Tokens**: The frontend uses JSON Web Tokens (JWT) for authentication. The access token is stored in local storage and sent with each request to the backend.
-- **Token Refresh**: The API client automatically refreshes the access token when it expires.
-- **Protected Routes**: The dashboard page is a protected route that can only be accessed by authenticated users.
+### Core Features Implemented
 
-## API Client
+- **Project Structure:**
+  - Modular file structure with `src/app`, `src/components`, `src/lib`, and `public` directories.
+  - Example components (counter, sample chart) for rapid prototyping.
+- **Authentication:**
+  - Google OAuth login flow
+  - JWT token management (access/refresh tokens)
+  - Automatic token refresh and session persistence
+  - Protected routes (dashboard, project pages)
+- **API Client:**
+  - Centralized API client (`lib/api.ts`) with interceptors for auth tokens
+  - Retry logic with exponential backoff and timeout handling
+  - Type-safe API calls using shared contract
+- **State Management:**
+  - Zustand stores for authentication, projects, chat, and UI state
+- **UI/UX:**
+  - Responsive design (mobile/desktop)
+  - Tailwind CSS for styling, DaisyUI for UI primitives
+  - Heroicons and Lucide for icons
+  - Recharts for charting
+- **Pages & Components:**
+  - Landing page
+  - Login page (Google OAuth)
+  - Dashboard (protected)
+  - File upload UI (CSV)
+  - Chat interface for natural language queries (initial version)
+  - Data visualization (charts/tables)
+- **Testing Setup:**
+  - Vitest and React Testing Library for unit/component tests
+  - Playwright for E2E test scaffolding
+- **Environment:**
+  - `.env.local` for frontend environment variables
+  - API URL, Google Client ID, Sentry, PostHog, etc.
 
-- **Axios**: The frontend uses Axios for making HTTP requests to the backend.
-- **Interceptors**: The API client uses interceptors to add the authentication token to each request and to handle token refresh.
-- **Retry Logic**: The API client uses a retry mechanism with exponential backoff to handle network errors.
-- **Type Safety**: The API client is type-safe, with types defined for all API endpoints.
+### Recent CI/CD and Linting Fixes
 
-## State Management
+- **ESLint Compatibility:**
+  - Resolved major CI/CD pipeline failures due to ESLint v9 incompatibility with Next.js 14 and `.eslintrc.json`.
+  - Downgraded ESLint to v8.57.0 for full compatibility with Next.js 14 and legacy config.
+  - Removed legacy `eslint.config.mjs` to avoid config conflicts.
+  - Ensured `.eslintrc.json` is the only ESLint config and is committed to the repo.
+  - Cleaned and reinstalled all dependencies to resolve stale/corrupt modules.
+  - Confirmed that `npm run lint` and CI/CD pipeline now pass with no config errors.
+- **CI/CD Pipeline:**
+  - Updated GitHub Actions to run lint, type-check, test, and build for both Node 18.x and 20.x.
+  - Ensured pipeline is robust to Node version changes and dependency updates.
+  - Added clear instructions for resolving future lint/config issues.
+  - Created a dedicated branch (`CI-CD-issues-fixed-20.X`) for all pipeline and lint fixes.
 
-- **Zustand**: The frontend uses Zustand for state management.
-- **Stores**: The application has separate stores for authentication, projects, chat, UI, and notifications.
+---
 
-## UI
+## 2. Backend
 
-- **Tailwind CSS**: The frontend uses Tailwind CSS for styling.
-- **Heroicons**: The application uses Heroicons for icons.
-- **Recharts**: The application uses Recharts for charts.
-- **Responsive Design**: The application is responsive and works well on all screen sizes.
+### Tech Stack

+- **Docker** (containerization)
 
-- **Landing Page**: A beautiful landing page that showcases the features of the application.
-- **Login Page**: A simple login page with Google OAuth integration.
-- **Dashboard**: A protected dashboard that displays user information and provides access to the application's features.
